The 2014 Corvette goes on sale this summer and shares only two parts with the current model, which is nine years old.

GM made the 2014 version lower and sleeker, saving weight by replacing the steel structure with aluminum. The interior gets a more modern look with new touchscreens.

The car gets a new 450-horsepower, 6.2-liter V-8 engine that can go to four cylinders on the highway to save fuel. A new seven-speed manual transmission is standard. Even the base model can go from zero to 60 miles per hour in under four seconds.
